Active-sampling approaches are commonly used for
personal monitoring, but are limited by energy usage and data that may
not represent an individual’s exposure or bioavailable concentrations.
Current passive techniques ...

Field trials in four distinct agricultural soils were conducted to examine changes to total recoverable and labile soil Cd and Ni concentrations with applications of commercial phosphate fertilizers. The edible portion o ...

The stability of citrate-capped silver nanoparticles (AgNPs) and the embryonic developmental
toxicity were evaluated in the fish test water. Serious aggregation of AgNPs was observed in
undiluted fish water (DM-100) in ...

I was honored to be the keynote speaker at the 30th Annual Society of Toxicologic Pathology Symposium “Toxicologic Pathology and the Immune System.” I had the opportunity to reminisce about events in the 1970s that set t ...

Contaminants used at low elevation, such as pesticides on crops, can be transported tens of kilometers and deposited in adjacent mountains in many parts of the world. Atmospherically deposited organic contaminants in the ...

The time-honored convention of concentrating aqueous samples by solid-phase extraction (SPE) is being challenged by the increasingly wide spread use of large-volume injection (LVI) liquid chromatography-mass spectrometry ...

A simple, fast liquid-liquid extraction method was developed for studying hexahydro-1,3,5-trinitro-1,3,5 triazine (RDX) biodegradation using small sample volumes. The method was tested
in vitro with anaerobic incubation ...
